' To alt whom it 'may concern.-

Beit known that I, IRA A. SABIN, ofLocnst Lane,

iniihe count-y of Indiana and in the State of Pennsylvania, have iuventedcertain new and useful Improrements in Steam Road-Vehicles; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompan ying drawing and letters of reference marked thereon making apart of this specification.

The nature of my invention consists in the construction and arrangement of a steam road-vehicle, as will be 'hereinafter fully set forth.

In order to enable others skilled in the art to which 'my invention appertains -to mathe and use the same, I

`will now proceed -to describe its construction and operation, ,referring to the .annexedxlrawing in which- Figure 1 is a longitudinal vertical section, and

Figure 2., a bttom view of my invention.-

lFigure 3 is a. section of the rear portion of the vehicle, showing a device for trimming the bed of the wagon..v

A represents the front axle, having at each end a wheel, B, which is provided on its circumference wit-h cogs, as seen in iig. 1.

The front axle A is connected with the 'rear axle C by'means of the perch-pole D, which is pivoted to both axles, to the ii'ont axle Ain a. recess, andto vthe rear axle in a slot on the same.

On the top ofthe front laxle A Vis secured-the fifth wheel, E, which is provided on its'upper slide, n car the rear. with a segmental rack, G.

.The king-bolt a, which pivots the perch-pole D to thc front axleA, passes also through the front bolster H, and a platform, I, placed o n top of the same.

In av recess on top of the front bolster H is placed a metal bar, J, -hlzoughwhich the king-bolt a also passes, said bar extending toward the rear, running parallel with the perch-pole D,'aud the bolt 11,' which pivots said pole in therear axle, passesalso through the rear end of the bar J.

The roar bolster K is also'pivoted by the bolt b passing through it, and has the wagon-bed L firmly attached to its upper side, said bed extending forward to lap over the rear end ofthe platform I.

Through the front end of the bed L passes a verti cal shaft, M, provided at its lower end, between the To the front side. of the rear axle C.' is attached aA semicircle, It, resting upon the-perch-pole D, said semicixcle being on its upper' side providedwith a seg-l Amentalrack, S, having thecogs on the inside. .This

rackis operated for the purpose of mcvingthe hind Awheels B' B,.when it is desired to turn short curves,

by means o f another segmentalrack, T, secured on the lower end of the shatt'U, whichpasses up through the bed L, and isprovidcd with a lever, V. This lever passes out through a slot in the rear end ofthe bed L, and is operated by means of another lever, W, which' is pivoted on the rear end of the hed, andheld in any position desiredhy means ofA the-ratchet-'bar X.

0n the side ofthe bed L is pivoted a cam-lever, y, for the purpose'of trimming the bed when the carriage ismoving on a side hill. This cam-.lever is held in any. position desired, in a iatchet-bar Z, as shown in iig. 2,- thecam operatingon theitop of thc hind axle C, as shown in fig-3.

There should bc one of th'ese'lcvers attached to each side of the bed'L. l

On the hub, on the inside of each front wheel, B, is formed or secured a cog-'wheelA', which is operated by means of another cog-wheel, O', placed perpendicularly above the same, its journals having theirbearings in standards D D'.

.The cog-wheels O' C' are turned by pitmen or' pistonsfrom an engine placed on the platform I. It will .thus be seen that the motive power is applied to the front wheels directly above the point where said wheels" rest on'thc ground, and hence there'can be noloss o'f power.

One o1' -niorewagons maybe attached to the hind axle C, for carrying heavy loads.

Having thus fully described my invention, What I claii n as new, and desire izo-secure by Let-- ters Patent, is

1. The arrangement,-on the side of the bed L, of thc cam-lever y and the ratchet-bar VZ, substantially7 as and forthe purposes herein set forth.

2. The arrangement of the cog-wheels B A C', standards D', segmentalracks G N S T, shaft M, lever O, ratchet P, shaft U, levers V WV, and ratchet-bar X, with their various parts, all constructed and operating substantially asset forth.

In testimony that I claim the foregoing. I have hereunto set my band this 23d day of March, 1870.'
